Determining the Water Content of Liquid Samples Using Iconic Liquid-based Capillary GC

Developing versatile, rapid, and accurate analytical techniques for the detection and quantification of water in a variety of materials remains an important and ubiquitous analytical problem. This article describes an effective and sensitive ionic liquid (IL)-based capillary gas chromatography (GC) method with thermal conductivity detection (TCD) to determine the water content in liquid samples.

A team of researchers has proved that the Ancient Mayans used tobacco. The discovery was prompted by the examination of several ancient Mayan containers from the Kislak Collection of the US Library of Congress for the presence of alkaloids.

LCGC is planning to publish the next issue of The Application Notebook special supplement in June.

How cells survive, replicate and maintain genome integrity in high NaCl concentrations has long puzzled scientists. A group of US scientists has conducted a series of experiments to determine how this occurs and discovered that cells are actually protected from these conditions by the ?gene deserts?, the 40% of the genome that are thought to serve no purpose.

Event news summary

Detection, analysis, and characterization of low-abundant metabolites remain an unresolved problem in metabolic studies. In this study, we report a novel approach to address this challenge. The current methodology is derived from the predictive multiple reaction monitoring (pMRM) mode available on triple-quadrupole linear ion trap mass spectrometry (MS) systems. The pMRM mode offers the highest sensitivity among various acquisition modes for studying trace levels of metabolites of the herbicide clomazone in plants. Additionally, this method allows for the identification of positional isomers of metabolites.

The forging of vehicle registration documents has seen a sharp rise in recent years, with the issue being particularly problematic in Brazil.

In comparison to other GPC/SEC detectors such as light-scattering detectors or UV detectors, viscometers need more care. It takes a longer time to get a stable baseline after changing from one solvent to another and the quality of the LC components plays an important role. Nevertheless, a viscometer is worth these efforts as it provides unique information that is not available with any other detector.

The results of a recent survery on stationary phases used in high performance liquid chromatography (HPLC) are revealed.

ARABLAB, the annual gathering of the analytical industry in Dubai, is once again recording substantial growth, not only in the Middle East but also throughout the world. With further hall space added for the 2012 event, there are even more opportunities for sellers and buyers to meet and discuss the latest products and services.
